To all whom t may concern Be it known that I, ANNA C. CLARKE, va citizenof the United States, residing at Scranton, county of Lackawanna, Stateof Pennsylvania, have invented certain new and useful Improvements inSewage Systems for Railway-Cars' and the like; and I do hereby declarethe following to be a full, clear, and eXact description of theinvention, such as will enable othersjskilled in ratus, together withmeans for regulating` the water pressure; and to provide an 1mprovedform of tank for receiving the sewage, associated with means for readilyattaching and detaching the tank with respect to the car andestablishing an efficient connection between the openings of the tankand the sewage waste pipe and the vent pipe when the tank is adjusted toposition in its supporting devices.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation partly in section of the body of a railwaycar having the invention applied thereto. Fig. 2 is an end view of thecar body, partly broken away to illustrate the relative arrangement ofthe parts of the sewage system. Fig. 3 is a longitudinal vertical'section through the improved sewage receiving tank. Fig. 4 is an endview showing a tank closure and its attaching means. Fig. 5- is an'endView of the tank with the closure removed. Fig. 6 is a section of oneend ofthe tank showing the means for securing Vthe closure thereto. Fig.7 is a sectional, view of the three- `way valve for directing the sewageinto the tank or to the open discharge. Fig. 8 is a detail view of' oneof the tank supporting beams. Figs. -9 and 10 are frontfand sideelevations of the tank supporting brackets by which the beams arecarried. v

Referring to the drawings, A indicates the body of a standard passengercar yp rovided with the usual toilet accessories, of which indicates thecloset bowl to the discharge end of which Yis attached a fittingprovided' with a three-waycvalve 2, one side 'of :which connects with a`sewage pipe 5 running toward the middle of the car and adapted to beattached its free end to the inlet of a sewage receiving tank, to behereinafter described. `The other side of the three-way valve isconnected with a pipe 3, provided with an open discharge to direct thesewage out of the car and on to or adjacent the right of way. The saidthreeway valve 2 is providedA with a suitable handle 4, which ispreferably extended to a point outside of the toilet compartment, so asto be accessible tothe proper person on the carv or train to operate thevalve to direct' the sewage either into the receiving tank or to theopendischarge on to the right of way. a

It will be understood that the invention .is not limited initsapplication to sewage from closet bowl, but may also be applied tothe'disposal of waste from basins, sinks, lavatories and otheraccessories of like nature common to railway-cars of the usual type t Asuitable storage tank 6 for flushing water is mounted at any convenientlocation in the vicinity of vthe toilet compartment and is adapted to beconnected with an eX- ternal water supply by means fof a suitably valved-pipe 7. The upper part of the tank vis provided with an outletpipe 10,which extends downward into the body of the tank to a point near thebottom thereof and is connectedfat its otherl end with'the usual inletvalve of a Hush tank 11,' which latter is connected by flush pipe 12with the bowl 1. In order to supply thel necessary pressureto force thewater from tank 6 into the flushtank j11 and to maintain anequalVpressure of waterat all times, the tank 6 is preferably connected by avalved pipe 8 with the air pressure system of the train brakes, properregulation of the airentering the tank being effected by a 'pressureregulator 9'located in pipe l@adjacent the bottom of the tank 6.

The sewage receiving tank 20 consists of a cylindrical shell, havingsecured at its ends, by rivets or other appropriate means, flanged rings21, each formed on its outer face with a seating rim adapted tocooperate with a corresponding seating rim on leakage.

the closure 24. Each of said end closuresy 24 is reinforced by crossedribs formed integrally therewith, the upper ends of which are providedwith hooks 26 adapted to engage and embrace lugs 22 on the rear face ofthe coperating ring 21 as particularly illustrated in Figs. 4, 5 and 6.The opposite edge of each closure 24 and each ring 21 is provided withregistering openings to receive a threaded bolt 28, the hole 23 in thering being screw-threaded, while the hole 27 in the closure is slightlylarger than the bolt 28 to admit of the latter being screwed intoposition and thereby draw the` seating rim on the closure into closecontact with the coperating rim of the ring 21 and effectively sealingthe tank against This construction of tank admits of the closures beingreadily removed for emptying the sewage and for flushing out the tank inthe most effective manner.

The under side of the tank 20 is provided at each end with a saddle 37riveted to the tank, said saddle having a relatively long flathorizontal bearing formed by pendent anges 41 having pin-receiving lugs38 eX- tending therefrom. Each of said saddles is adapted to slidablyengage an inverted channel bar 43, the opposite flanges of which aresuitably notched as at 44 to receive locking pins 39 by means of whichthe tank is locked securely in position to the two beams 43. Said beams43 are detachably supported in the forked ends 41 of brackets 40, whichare disposed in pairs on opposite sides of the car and the ends of eachbeam 43 are locked to the brackets by pins 42 passing throughperforations in the forked ends of the brackets 40 and engaging notches44 in the pendent flanges of the beam. Said beam is strengthened bymeans of a truss rod 45 which is secured to the beam 43 by means of endblocks 47 and a central casting 46. The blocks 47 are provided withlongitudinal perforations adapted to receive the end of a bar to admitof the beam being raised and lowered to position by the man whose dutyit is to remove the full tanks and replace them with empty tanks.

The connection between the tank and the sewage pipe leading from thecloset bowl or other toilet accessory is effected by means of theconstruction shown in Fig. 3. The discharge end of the sewage pipe orconduit 5 is tapered as at 5 to make a close airtight lit with a rubbergasket or washer 31 which is securely held between a seating ring 30riveted to the tank and coupling flange 32 secured to said ring by meansof bolts or the like. The coupling flange 32 is provided with an openingsomewhat larger in diameter than the end of the pipe 5 and said openingis screw-threaded on its interior to receive a screw-threaded plug toseal the tank when the same is removed from the car and while it isbeing taken to the proper place to be emptied. The vent pipe 33 which ispermanently attached to the car and passes upward through the wallsthereof to a, point above the roof, is attached to the tank by a similarhermetic seal consisting of a rubber gasket 35 cooperating with thetapered end 33 of said pipe 33, said gasket being held between a seatingring 34 riveted to the tank and an interiorly threaded cap 36 adapted toreceive a plug to seal the vent opening in the tank when the latter isremoved.

In applying the invention to its intended use, the tank is secured tothe car by two workmen, each of whom inserts a bar in the opening inblock 47 and lifts the corresponding beam 43 until the correspondinglocking pin 42 can be withdrawn, after which each of the beams 43 islowered until its end rests upon the ground adjacent the railway track.The empty tank is then applied to the beams so that the saddles 37engage the two beams and the said tank is shoved forward along the beamsuntil the openings in the lugs 39 of the respective saddles comeopposite the notches 44 in the beams 43 at which time the locking pins39 are passed through the ears 48 and the notches 44, 44, whereby thetank is securely locked to the beams. The workmen then lift the ends ofthe respective beams by means of the bars engaging the blocks 47, untilthe free end of each beam engages the forked end 41 of the coperatingbracket 40, whereupon the locking pins 42 are passed through theperforations in the forked ends of the brackets and notches 44 in thebeams, and the tank andl its supporting beams thereby securely locked inposition. It will be apparent that the tank may be applied to or removedfrom position from either side of the car, inasmuch as the supportingbeams 43 are attached to brackets 40 in the same manner at each end. Asthe tank is thus moved to position, the sewage inlet opening and thevent opening to the tank are both brought into registry with the liXedtapered ends of the sewage conduit 5 and the vent pipe 3 3, with theresult that said tapered ends are forced into close air-tight engagementwith the rubber gaskets 31 and 35 respectively, mounted adjacent saidopenings. When the tank is to be removed from a car, the operation isreversed, that is to say, the beams 43 are cast loose from their bracketvsupports on one side of the car and the Vfree ends of the beams droppedto the right of way. This separates the tank from the' pipes 5 and 33,after which the fastenings between the tank saddles and the beams 43 areremoved and the tank slid along the inclined ,beams 43 until free ofthe` same, when it can belifted by the workmen and conveyed to the placeof ultimate disposal of the sewage. After a full tank has been removed,an empty tank is applied to the beams and the latter adjusted to lockedposition, as hereinbefore described. As soon as the full tank has beenremoved, the sewage inlet opening and the vent opening are closed bymeans of screw plugs inserted by the workmen in caps 32 and 36respectively, if found necessary. The full tanks may be convenientlyhandled by suitable trucks equipped with cranes for lifting the tanksthereon, and, of course, may be transported to any suitable orappropriate place for ultimate disposal of the sewage. The tanks areemptied by removing one of the closures 24, after which the otherclosure 24 may alsobe removed and flushing water turned into the tank,open at both ends, t0 effectively clean the tank.

The tank is intended to be used in all localities where contamination ofthe soil or of streams would be likely to occur from sewage dischargedfrom the car, and when traversing such localities, the three-way valve 2is turned to discharge all of the sewage from the car into the tank.When, however, the car is passing through sections where contaminationof streams cannot occur or where contamination of the soil of the roadbed is immaterial, the three-way valve may be adjusted by the attendanton the car to direct the sewage by way of pipe 3 to the open discharge.

The entire system as hereinbefore described, is adapted to be applied toany standard railway car or similar conveyance, without materiallychanging the usual form or arrangement of standard sewage appliances, itbeing necessary only to attach the tank supporting devices to the underframing of the car, to mount the water storage tank and its air pressureconnection at some point convenient to the toilet compartment, and toapply the three-way valve and its connected conduit pipes to thedischarge outlet of the bowl or other toilet appliance.
